gniibe tracked the problem down to a fully valid change in GnuPG
(gnupg commit 12af2630cf4d1a39179179925fac8f2cce7504ff).  He wrote:

This is the first instance for estream to do READ and WRITE
(in the history of the code > 10 years :-).  In the [gnupg] function
agent_write_private_key, the pattern is:

    es_fopen
    es_fread
    es_fseek
    es_fwrite

which should work well, but if results core dump by assertion failure
in the function es_flush of libgpg-error.

* src/estream.c (func_mem_create): Round up memory limit.
--

This is required so that giving a memory limit to es_fopenmem won't
fail if it is below the block size.
